I think Sony dropped the ball by not having at least a dictionary function. If the whispernet and access to the Amazon store options were unavailable to me , then I would go for a Cybook before I'd pick up another Sony Reader. I have found that I use the dictionary a lot more than I thought I would.

Of course, being a victim of public education may have something to do with that.

When I had a Sony I didn't think that dictionary lookup was that big a deal. Now I have a CyBook, though, I find myself using it all the time, especially when reading Dickens, who uses a lot of words which are no longer in common usage.

Question to Kindle owners: does Igor's "Mobi hack" allow you to use any of the commercially-available Mobi dictionaries on the Kindle? Has anyone tried doing this?
